How to Find Density in Chemistry

How to Find Density in ChemistryOne of the major challenges in the field of Chemistry is the ability to learn how to read a graph of its density. This might seem like a relatively simple task, but if you do not know how to do it correctly, you can end up wasting your time and money. With the many different types of graphs that you will come across on a typical chemistry course, it is important to understand how to properly interpret the data.The most common type of graph that you will find is a one dimensional graph. There are many different levels of intensity that can be found on this graph. If you will notice, the density of the material is always plotted in a straight line. There are several reasons for this.When studying the graph, it will help you to identify the consistency of the material that you are studying. A variation of the material will have a different density than the original. Knowing how to find density in chemistry will also help you predict how well a material wi ll react to a reaction. If the material is not uniform in density, then it should be studied differently.There are several different ways that you can plot a graph of density. The simplest way of all is to draw a vertical line through the middle of the graph. Each line represents one level of density. With this type of graph, the density can easily be compared to another.Another type of graph that you will find is called the area graph. This graph consists of an entire sheet of graph paper on one side. The number of lines on the side will increase as you go up the material. This type of graph will show you the consistency of the material that you are studying.If you want to learn how to find density in chemistry by yourself, then the simplest way is to study each graph from top to bottom. With this method, it is best to practice on a blank sheet of graph paper. You want to draw a line between each of the lines of the graph. Once you can line up the graph properly, you will be able t o draw the lines without any problems.You will also need to be careful with the density. The values of density may vary from one test to the next. Therefore, if you start by graphing all materials at once, then you might not be able to correct the values that you have already determined. Therefore, it is best to graph the materials after you have determined their density values.As you can see, learning how to find density in chemistry will allow you to better understand and prepare for your advanced courses. The density graph is one of the easiest graphs to understand and learn how to read.

Vocal Health Tips for Fall and Winter Part 1

Vocal Health Tips for Fall and Winter Part 1 Suzy S. Were in the height of the Fall season now, and Winter will be here before you know it! Before you get swept under by the holiday hustle-and-bustle, take a moment to review these vocal tips to keep you healthy during these colder months, courtesy of Seattle vocal teacher Nicole G... It’s my favorite time of year! The air is crisper and cooler, you’ve located your cozy fall jacket, you’ve started making hot oatmeal for breakfast. The heat may be turned on in the house, and you might be craving a hot cup of coffee to keep you awake on early morning routes to work. Or, you are managing a hectic school schedule, juggling homework, exam studying, play or musical rehearsal, a part-time job, sports practice, community service, college coursework, family time, holiday preparations, a social life… you name it! Busy. We are ALL busy people in our own ways, especially during this time of year. Yet even in the midst of this energetic daily buzz of life, it is EXTREMELY important to be taking care of our bodies, and clearly, our voices! Sometimes we get caught up in the craziness of our schedules. As singers and as people who use our voices constantly every day, we need to be aware of how to tend to our special, personal instruments. Below are several vocal health tips to help you take care of yourself in the best possible manner 1) Hydration is essential! Drink plenty of water. It is recommended to drink eight 8-oz. glasses of water a day. During the winter months, the air is drier, with little humidity or moisture in the air. It is especially important to maintain hydration in the winter months. You may be in the bathroom more frequently, but your vocal folds will be MUCH happier. If you drink coffee, tea, alcohol or any liquid containing caffeine, it is vital that you drink one glass of water (or more) to counteract the caffeine. This recommendation applies to everyone, not just singers! Caffeine is a stimulant, and while it keeps our energy up, it also dries out our vocal folds. 2) Strive to get enough sleep. When we are busy, sleep is often the first thing that gets the short stick. Everyone requires a different amount of sleep in order to function. In the same vein, a lack of sleep has a direct effect on the functioning of the voice (and your brain!). I highly encourage taking naps, if possible. It’s important to listen to your body’s needs. 3) Avoid using the phone at night. Most people arent aware of how they are using their breath and throat while speaking on the phone. When we’re calling a friend, study partner, relative, coworker or significant other, we are usually in a very different mindset than when we’re in a voice lesson or practicing. Because we don’t need to project, and because we have other things on our minds, we may fall into the habit of talking lazily or not loudly enough into the mic of a phone, which can tire out the voice rather quickly. By talking lazily, I mean using less air than we are equipped with, or unintentionally tightening the throat. 4) Be aware of your posture. Are you carrying a heavy backpack around between classes? Are you standing or sitting at a work desk frequently during the day? We often collapse our chests while carrying something heavy or while sitting in front of a computer. Keep checking in with your body throughout the day to make sure you stay upright and are leading from the sternum (the breast bone). The head can also unintentionally tip backward or jut forward. It’s best if your head feels as if it is floating on your spine. 5) Avoid clearing your throat during speech or after coughing; swallow instead. As the climate changes, its easy to feel “under the weather,” and we may start to clear our throats more. When you clear your throat, you are basically smacking your vocal folds together, which is abrasive. This can create a “repetitive stress injury” in the voice box, known as the larynx. Swallowing is a much healthier alternative to clearing your throat.

Princeton University A Student Perspective

Princeton University A Student Perspective The tutors behind Varsity Tutors are not just here to teachtheyre sharing their college experiences as well. Adam received his bachelors degree in religion and theater in 2011 from Princeton University. He is currently a Los Angeles tutor specializing in English tutoring, French tutoring, social studies tutoring, and much more. See what he had to say about his time at Princeton University: Describe the campus setting and transportation options. Adam: The Princeton University college campus is very, very walkable. It is a large campus, but lots of students have bikes and there are plenty of bike racks around the dorms. The campus is also very safe. It is an open campus, but there is a Public Safety team that patrols the campus and there are emergency Blue Light phones if you ever feel unsafe. It is also an absolutely beautiful campuslike walking through a finely manicured garden at Hogwarts. How available are the professors, academic advisers, and teaching assistants at Princeton University? Adam: All the teachers I had offered office hours. It is harder sometimes with the larger courses that have big lecture groups, but there are grad students and what we call preceptors who help with group discussions and assignments when there is difficulty. How would you describe the dorm liferooms, dining options, location, socialization opportunities with other students? Adam: I loved my dorm life. I was in the dorm that was most remote from central campus (Forbes College), which I think made all of us living there grow closer than most by necessitybecause walking to the closest dorm from there takes about 10 minutes. There are dining options for all four years of school, and plenty of social events planned by the Residential College advisers. Which majors/programs are best represented and supported? Adam: I was a Religion major. It is a well-known program at Princeton and was particularly popular in my class. The most popular majors amongst my friends while I was there were engineering, economics, history, english and comparative literature. The university provides wonderful resources for research and support for all majors. How easy or difficult was it for you to meet people and make friends as a freshman? Does Greek life play a significant role in the campus social life? Adam: Greek life is certainly part of the social scenebut it is by no means the cornerstone. The social scene at Princeton is dominated by the Eating Clubs, which are essentially co-ed fraternities where you eat your meals, hang out, study, and have events, but you dont live there like with Greek houses. The dorm life is particularly geared towards encouraging interactions amongst freshman, and those who live nearby. I had no trouble making friends freshman year as I was involved in several extracurricular activities. That was the best way for me to make friends because we had so much in common, and I am still very close with most of my college friends. How helpful is the Career Centerand other student support services at Princeton University? Adam: The Career Center at Princeton is certainly available to all students. As far as I know, they can be very helpful. I had no personal experience with the Career Center as I knew I would be going into a profession that is not as traditional. Finance companies, in particular, recruit heavily at the university. There are career fairs, and also many opportunities to meet with recruiters and apply for internships throughout the year. How are the various study areas such aslibraries, the student union, and dorm lounges? Adam: Almost all of the study areas at Princeton are just beautiful. Firestone Library is gorgeous and hugethere are several floors and many areas within it. There are also study areas and computer clusters in the dorms, Art Museum, Frist Campus Center, and Eating Clubs. There are so many places where one can study that I never had trouble finding a quiet place to work. Princeton students are also very studious and keep quiet in public work spaces. Describe the surrounding town. Adam: Princeton is a beautiful little college town in central New Jersey. There are some great affordable places to eat (Zorbas Greek was always my favorite) and two famous ice creameries that are very popular with students and visitors alikeThomas Sweets and The Bent Spoon. There are also some great upper-scale restaurants (to take your folks when they come visit!). How big or small is the student body? Were you generally pleased or displeased with the typical class sizes at Princeton University? Adam: The student body is roughly 1,200 per class (at least it was when I was there). I was generally pleased with the class sizes. Seminars are a great option for concentrated study in a smaller environment. I once took an entire semester about Christian Eschatology that met once a week for three hours in a class size of roughly eight. It was probably my favorite class at Princeton. Focused study, wonderful attention from an expert and great readingsI loved it. Describe one memorable experience with a professor and/or class. Perhaps one you loved the most or one youregretthe most. Adam: I did a lot of theater at Princeton. I had one teacher for two semesters who also directed me in several productions. He was incredibly helpful to me in growing as an actor, artist and person. He made himself available to all his students, and even supported us long after graduation. I had the chance to work professionally with him as well, and he was very supportive of all his former students after graduation. I will never forget how much the Arts faculty at Princeton puts into their work, and how available they make themselves to their students. I did a lot of work with the department of Theater and Dance, and all the teachers I had were passionate professionals with so much to share. Check out Adams tutoring profile.

Area of A Cone

Area of A Cone Cone is a geometric figure with a fixed vertex and a circular base. The curved surface area of the cone = * r * s. Here r is the radius and s is the length of the slant side. Slant side, s = (r2+h2). The height h of the cone from the vertex of the cone and the radius r of the circular base make a right angle. Example 1: What is the curved surface area of the cone which has the base radius r of 3 cm and height 4 cm? The base radius of the given cone is 3 cm, i.e. r = 3 cm. The height of the cone, h = 4 cm. The slant height of the cone, s = (r2 + h2). s = (32 + 42) = (9 + 16) = 5cm . Area of cone = * r *s This makes the solution = 3.14 * 3 * 5 = 47.1 cm2 Hence, curved surface area = 47.1 cm2 approximately. Example 2: What is the curved surface area of the cone which has the base radius r of 5 cm and height 12 cm? The base radius of the given cone is 5 cm, i.e. r = 5 cm. The height of the cone, h = 12 cm. The slant height of the cone, s = (r2 + h2). s = (52 + 122) = (25 + 144) = 13 cm . Area of cone = * r *s This makes the solution = 3.14 * 5 * 13 cm2 = 204.1 cm2 Hence, curved surface area = 204.1 cm2 approximately.

An Introduction To A Level Biology Revision

An Introduction To A Level Biology Revision All You Need To Know About Studying Biology A Level ChaptersBiology A Level Curriculum And TipsA Level Biology Past Papers Exam BoardsGuides And Resources For A Level Biology RevisionExam Timetables And GradingLooking Ahead To The A Level Biology CourseNow that you have finished or are soon to complete your two-year GCSE Biology course, you will already have grasped some of the fundamental details and knowledge required by the subject.During your GCSE, you will have had the opportunity to learn about a variety of biological functions including the human body, organisms, evolution and the environment, all taught with everyday relevance so that that you were able to draw much more from the content. Hopefully, by now, you will have some idea of just how much Biology affects our everyday lives and will be eager to learn more.At A Level, you will get a chance to look at evolution again. Photo on VisualHunt.comThe A Level course that you are about to embark on is no different to the GCSE one in that it too offers an array of fascinating an d useful information about our bodies and the world around us. Also similar is the duration of the course, which takes two academic years to complete in full. The main difference, however, is the level of detail at which you will explore these biological concepts.As a result, by opting to study Biology at A Level (even if you only complete your AS Level and then have to drop the subject for one reason or another), you will be up-skilling your existing knowledge and becoming much more aware of the ins and outs of our bodies as well as how we fit in to the work around us.What’s more, with all of the additional Biology learning under your belt, you will be on track to apply for and be accepted on a further education course related to the science as well as a career in Biology further down the line.More Reasons To Stick With Biology A LevelBecause it is known as the Science of Life, Biology is relevant to all students and is a key transferrable subject. Unlike studying English or Hist ory, for example, which are taught in the context of the country in which they are being taught, a biology  tutor teaches about all human beings and explores the basics of our environment.So, no matter which country you end up living in or in which climate, you will still have a reasonable understanding of how the nature around you works with a qualification in Biology, and how you as a human being interact with it and can nurture it.No matter where you are in the world, Biology is still the same study of life. Photo by astro_matt on Visual huntWith many fascinating experiments waiting for them, Biology students can benefit from acquiring a wide range of practical skills through hands on work, with tests being more sophisticated than in previous years of schooling. They will be encouraged to not only study how Biology works, but how elements of the Science can be used to solve problems. As such, a number of other skills play a big part in the process of studying Biology, like Mathem atics, Physics and Technology.Biology is a great subject to have under your belt if you dream of a career in Medicine, but is not limited to this field of expertise. Many Biology students go on to professions in areas like Marine Biology, Zoology, Teaching, and much, much more.Search for an A Level biology tutor now.Biology at A Level is offered by AQA, WJEC, Eduqas and OCR, among others. Below are two of the most popular exam boards for Biology A Level.AQA A Level Biology Past Papers (7401, 7402)At a glance, this linear specification offered by AQA covers a range of core topics such as Biological Molecules, Cells, Genetic Information, Energy Transfers and Gene Expression, the last two being taught at A Level only.The AS Level course is split into two exams, each worth 50% of the final grade and lasting 1 hour 30 minutes. The second year, however, is assessed over three written exams, each taking 2 hours to complete and making up 35%, 35% and 30% of the final mark respectively.Look up for biology online tutoring now.OCR A Level Biology Past Papers (H020, H420)This specification leans on the practicality of Biology for students and integrates problem-solving to help pupils understand biological concepts and scientific methods. Like the above, the course is split between the two years of study.The overall course is said to refresh the popular themes from GCSE Level specifications and embed new modules centred around answering the all important question in more detail: How does Science work?Using The Exam Boards' Biology Past PapersDoing past papers is probably the best form of revision you can do in the run up to your Biology A Level exam, as it gets you used to formulating exam-style responses that meet the required level of sophistication for this advanced course.By using past papers properly, you can work on improving your technique, thus growing in confidence. However, it is no good simply reading past paper questions or just jotting down answers haphazardly . Here are some tips on how best to use these resources.How To Use Past Papers For Successful RevisionIn the run up to your end of year exam, your teacher may organise a mock exam for you, or set a classroom task which simulates an exam. This will help you familiarise yourself with the exam setting once again.Note: You may find that your A Level exams are even more strict when it comes to taking materials in with you.It is even more important to revise thoroughly for A Level exams as you will be expected to offer more knowledge than ever before. Photo on VisualHunt.comExam-taking is not all about what you know and how well you cope under pressure though. A very important aspect of being assessed is how effectively you communicate your responses. Consulting past papers can enhance your ability to respond well and can guide you to gaining extra marks by teaching you what it is the examiner is looking for.So, familiarise yourself with the types of questions that are commonly set and as k yourself what it is they are trying to get out of you.Approaching the exam with some level of confidence is encouraged but pupils need to be realistic and educate themselves on the mark scheme. Not enough emphasis is placed on this document, but the fact that it essentially tells you in so many words  how to pass your exam speaks for itself!Guides And Resources For A Level Biology RevisionThe BoardsHelpful Biology revision resources can be found on each of the exam boards’ websites. For example, AQA’s website has a page linking to teaching resources (equally useful as documents aimed at students if used correctly) as well as documents for students to download.OCR, meanwhile, proposes high-quality resources which can be searched by qualification type and resource type, to help you find the right documents for you. You can also download a skills guide from their site to match your personal skills to particular qualifications. This could be a worthwhile activity for those unsure where they are heading after the A Level course.Reminder: Do not miss the past papers, which as you now know can be a great help when it comes to preparing for exams.Revision WebsitesIf you have not yet come across it, be sure to visit BBC Bitesize for your learning needs throughout the course.This website, dedicated to UK students of all ages and taking a variety of exams, will help to break down the topics in an easy way and will additionally make learning that little bit more fun.As well as BBC Bitesize, Revision World is a fantastic place for students to go during times of need. This easy to use website offers students study help, coursework assistance, essay writing tips, past papers and many more valuable resources to make revising easy and enjoyable.Getting hold of revision materials online is brilliant as most resources are easily accessible at the click of a button, plus they are usually straightforward and free (except from having to occasionally sign up), which is an adde d bonus.Exam Timetables And GradingTimetables for compulsory exams like A Levels are released up to two years in advance but are subject to amendments until the final timetables are confirmed, usually in the 12 months prior to the assessment period.Why not use this to your advantage by planning revision sessions to fit around your exam schedule, so that you can visualise how the weeks leading to the exam period will pan out? Be sure to plan and do everything you want to do before reaching the date of the exam.For instance, if you want to visit a particular Science museum, then make sure you do not waste any time and get this booked into your diary now. And, speaking of diaries, it is a good idea to highlight key dates in your diary, planner or on a calendar in your room to maintain your focus during those last weeks gearing up to exams. Fail to prepare, prepare to fail!

Initiatives To Increase College Graduation Rates

Initiatives To Increase College Graduation Rates Until recently, America has led the world in producing college graduates. President Barack Obama has vowed that America will retake the lead by 2020, winning the support and funding of many organizations. Higher-education groups have targeted many different groups and demographics, always trying to promote education to increase Americas overall number of college graduates. These groups have promoted the importance of this initiative to community colleges, public universities, African American students, college dropouts and other demographics. Now, education groups and the Obama administration are targeting Hispanic students to increase Americas overall number of college graduates, hoping to reach its 2020 goal, according to an article in the Washington Post. This concept was presented by non-profit organization Excelencia in Education, along with the Bill and Melinda Gates Foundation, the Lumina Foundation and other major education advocacy groups. This initiative, called Roadmap for Ensuring Americas Future, suggests that Hispanics will have to earn 5.5 million college degrees by 2020 for America to reach its goal of having 51 percent of the population being college or postsecondary degree graduates. The 51% college graduation rate is fairly low, compared to other organizations goals of 55-60%. Hispanics are now being targeted because they are the fastest growing minority group in America. The Hispanic population is projected to triple in size by 2050 and represent 29% of the U.S. population, all according to Pew Research. Hispanics are also now being targeted because of their historically-low college-completion rates. Other cultural factors such as not wanting to incur college-loan debt also contribute to low-graduation rates. State and institutional initiatives that focus on those (Hispanic) students can make a big difference, the Excelencia in Education group said in a release. Research from the Excelencia in Education group indicates that Hispanic students often enroll in college later on in life and at community colleges closer to their homes. This is great news for Hispanic students as many organizations will take a personal interest in increasing the number of Hispanic college students and graduates. Organizations are likely to create scholarships and other resources for prospective Hispanic college students. Other than targeting specific groups and demographics, education organizations are also trying to create programs to better retain current, working college students, increase college-preparatory and dual-enrollment programs and simplify two- to four-year transfers and guarantee need-based aid to deserving students.
